We produce wire mesh demister pad / mist eliminator for over 10 years. Demister pad is also known as mist eliminator, wire mesh separator or wire mesh blanket. It separates mist contained in a fluid. Among all the materials for demister, PTFE / teflong is a kind of high corrosion-resistant one, which can withstand strong acid, strong alkali and other corrosive media. You can expect excellant performance when the operating temperature is under 230 °C.

1. How does a demister pad work?
(1) A vapor stream carrying entrained liquid droplets passes through a demister pad. The vapor moves freely through the knitted mesh.
(2)The inertia of the droplets causes them to contact the wire surfaces and coalesce.
(3)The large, coalesced droplets formed in the mesh ultimately drain and drop to the vessel bottom.
Uses of demister pad
Reduce loss of valuable chemicals: demister pads markedly cut glycol, amine, or solvent consumption in absorption and regeneration towers.
Increase throughput capacity: demister pads allow a significant increase in throughput anywhere gases and liquids come into contact in process equipment.
Improve product purity: demister pads prevent contamination of side draws and overheads in refinery atmospheric and vacuum towers and other distillation columns.
Minimize contamination: demister pads can prevent the poisoning of expensive downstream catalysts or provide boiler feed water quality condensate from evaporator overheads.
Provide equipment protection: demister pads protect turbine, blower, and compressor blades, which can eliminate serious maintenance problems.
Reduce air pollution: demister pads help diminish droplet emissions to environmentally acceptable levels.
